1.3Construction Details

The SANLORENZO 72 Yacht is made of longitudinal structure composite materials with transverse rings and longitudinal reinforcements along the entire length of the hull, starting from the engine baseplates, all being arranged below the platform level.

The Yacht is fitted with three watertight bulkheads, the two ones arranged to separate Engine Room from the living quarters and the afterpeak respectively, and the third one acting as a forecollision bulkhead.

Stern shoes, engine discharges and ventilation ducts are made an integral part of the hull.

Upper deck and superstructure are generally made of “sandwich” laminated material with a core of closed cell PVC.

The hull is fitted with a partial double bottom housing the fresh water structural tank and the gray & black water tanks.

3 Construction Materials and Design Criteria

3.1General

Composite materials (GRP) are used for hull, decks and superstructure construction.

The laminate mechanical and chemical features will be checked and tested according to the classification society’s procedures.

The Yacht will be constructed using vinylester resins (for the first three layers of the hull’s laminate) and isophthalic polyesters for the plating, structures and GRP ancillary parts. The neopentylic type of gelcoat is used; depending on their use, reinforcement fibres are mats, multiaxial and unidirectional glass rovings as shown on the structural drawings approved by the Classification Society.

The PVC used as core in the sandwich is closed cell type with a density between 50 and 90 kg/cu.mt.

Shaping and scantling of the structure according to the state of the art for design and construction of GRP yachts of this type in order to ensure a maximum structural continuity and the best efficiency for vibration and noise reduction.

3.2 Hull

Hull plating of various thickness single skin, in accordance with the regulations. The structure is longitudinal with transverse bulkheads and keelsons as the main bearing structures. Three watertight bulkheads partitioning the yacht into four watertight compartments as follows:

• Afterpeak

• Engine Room

• Living quarters

• Chain locker

All piping and electrical cableways passing through the bulkheads will be watertight.

The hull is fitted with a partial double bottom housing the fresh water and the gray & black water structural tanks. A suitable number of bilge wells will be fitted.

The bilges are gel-coated.

The transom has been designed in order to accommodate - in this section of the hull - the rear swimming platform and the watertight hatch giving access to the afterpeak.

Gas pipes and ventilation ducts are made from GRP integrated into the structure; the gas pipes run from the Engine Room to the transom and have been designed and built in order to obtain an effective silencing of the Main Engine exhaust pipes. Flam-proof gelcoat and selfextinguishing resins are used whenever required.

Special reinforcements will be placed in way of the propelling machinery and manoeuvring equipment baseplates, such as engines, generators, shafts, arms, rudders and bow thrusters.

The underwater body will be treated with antifouling paint manufactured by a leading company (“International” or equivalent) with complete anti-osmosis epoxy cycle.

3.3Upper Deck

Deck plating is made of various thickness sandwich as per regulations; the structure is longitudinal with carlings, transversal bulkheads and props as the main bearing structures.

A watertight hatch will be built near Engine Room to facilitate assembly and disassembly of machinery.

Special reinforcements will be made near manoeuvring parts, such as windlasses, warps, cranes, hatch and gangway mechanisms.

All piping and electrical cables passing through the deck will be watertight.

3.4 Superstructure

The plating of the superstructure is made of various thickness sandwich in accordance with regulations; the supporting structure is transversal, with longitudinal carlings fitted for additional support.

A watertight hatch will be built on the fly bridge in way of the Engine Room to facilitate assembly and disassembly of machinery.

The parts to be subject to high stress, such as side doors and the base of the roll-ball will be suitably reinforced.

3.5 Structural Bulkheads

Structural bulkheads are fitted according to the partition envisaged as per general plans and the structural requirements. As previously stated, three bulkheads will be watertight.

The collision bulkhead will be fitted as required by the Classification Society. The bulkheads will generally be made of plywood sandwich with polyethylene core (Laricross or equivalent) or marine plywood of suitable thickness.

An escape will be fitted at the bow port side according to the Classification Society’s requirements.

3.6 Tanks

The tanks are made according to a breakthrough system, consisting of a metal case lined with composite. The metal case has a 5 mm thickness, and is lined with a “sandwich” envelope consisting of a 15 mm PVC layer glued to the metal tank and a vynilester GRP layer of about 6 mm thickness.

Thanks to this solution a double waterproof seal of the tanks is obtained, so as to avoid any leakage. Moreover, the “structural” tanks being perfectly integrated with the hull structures, allow for maximum tank volumes with a minimum space occupation.

The three contiguous gas oil tanks are built with an aluminium inner case and form the Engine Room fore bulkhead. They are fitted with all the required vents and connections.

The three gray & black water collection tanks are built with a stainless steel AISI 316 inner case and fitted on the hull bottom. They are fitted with all the required vents and connections.

The drinkable water tank is built with a stainless steel AIS 316 inner case, in order to protect the drinkable water from the polluting agents.

Moreover, the tanks located on the hull bottom are separated therefrom in order to prevent any possible perforations and the relevant leakage in case of little collisions to the vessel bottom.

All the tanks undergo a pressure test as per Classification Society’s requirements.

3.7 Insulation

Engine Room will be fully soundproofed and heat insulated.

More specifically, the fore bulkhead - partitioning the Engine Room from the living quarters – is made up by means of the gas oil structural tank. This tank acts as a cofferdam; moreover the fluid inside increases the soundproofing through the sound wave abatement.

This bulkhead is insulated by means of the following soundproofing and heat insulation material package:

• On the living quarter side, a “Lariphon” panel with cork-rubber insert, having high soundproofing and sound wave damping capacity, as well as the best thermal insulation characteristics

• (“Iso-T”) viscoelastic material blocks between the above-mentioned panel and the structural tank to ensure the uncoupling of both elements

• The bulkhead side against the Engine Room will be coated with a lead sheet and a layer of high density rock wool, finished with a white sheet panel

The walls and ceiling in Engine Room will be also insulated with high density rock wool and layers of lead.

Main Engine exhaust pipings are insulated with the “CR” Cofeme system, featuring a tight waterproof seal, no heat bridges nor heat reflection actions. Moreover, this system is selfextinguishing, has a very good resistance to flames, lubeoils and fuels and under operation it does not release vapours nor dangerous toxic matters.

The ventilation pipes will be covered “Pavicell” panels.

The thermal insulation of the superstructure and bulwarks will be made by means of a layer of fiberglass covered by an aluminium sheet.

3.8 Teak Deck Coverings

Upper deck laid with top quality teak, with 12 mm thick x 50 mm wide staves, bonded to the deck. A teak grating with convenable drainage is housed both on the swimming platform and on the down steps therefrom.

All watertight doors are made of aluminium and steel with hand wheel closing system and stainless steel arrestor locking system. The seals are made of silicon.

Watertight hatches on the deck are made of solid wood or steel and glass, with manual closure and open locking system.

3.10 Windowing

Windows are in tempered silked glass with the thicknesses and characteristics as per Classification Society’s regulations.

Windows in wheelhouse are made of stratified glass, fitted with intermittent wipers.

The flybridge windshield is made of tempered glass with steel frame.

All fixed windows in the superstructure are mounted by bonding flush with the superstructure.
